Questions tagged [windows]

Windows is the brand name for a series of operating systems from Microsoft. Current versions are Windows 10, Windows 11, Windows Server 2016, Windows Server 2019, and Windows Server 2022. Instead of tagging a post "Windows", try to use a tag for a specific version.

Introduction

Windows is a family of operating systems developed by Microsoft. Originally a graphical add-on for Microsoft DOS, Windows is currently the market leader for operating systems on the desktop.

Today there are several branches of Windows:

  • Windows for desktops, notebooks, and tablets
  • Windows Server, for servers
  • Windows IoT, for embedded devices such as point of sale, kiosks, and signage

Tag recommendations

If your question is version-specific, consider using a version-specific tag.
